摘要
煤燃烧过程中排放的SO2和NOx是造成大气污染的主要成分,如何经济有效地控制二者的排放量是我国乃至世界节能减排领域中急需解决的关键问题。文章综述了国内外目前开发的液相同时脱硫脱硝技术,分析了各法的工艺特点和存在的问题,包括氧化吸收法、还原吸收法及湿式络合吸收法等,并对研究和应用进行了展望,对湿式脱硫脱硝一体化技术的应用具有一定参考价值。
The main components of air pollution is SO2 and NOx emerged in the coal combustion process, and the key issue to be soluted urgently is how to effectively, economically control SO2 and NOx emission to meet energy - saving and emission reduction objective at home and abroad. The development of simultaneous desulfurization and denitrogenation technologies in aqueous solution over worldwide was summarized and the characteristics of oxide absorption technology, absorption reduction technology, wet complex absorption technology and problems of them were analyzed . The research and application of simultaneous desulfurization and denitrogenation technologies in aqueous solution was prospected. The paper has a reference value to application of wet desulfurization and denitrogenation integration technology to some extent.
